A farm machine includes a machine body, an awl head and a control module. The machine body has a body and two stepper units installed on opposite side of the body respectively, and the stepper units drive the body to move. The body also has a pivoting unit and a swing unit, the pivoting unit installed on front side of the body and connected with the swing unit, the swing unit is wiggly to drive the pivoting unit. One end of the awl head is pivot on the pivoting unit. The swing unit controls the awl head to swing in an axial direction with respect to the machine body. The control module installed on the machine body to drive the machine body and the awl head.一種農作機具,係包含:一機身,具有一機體及二步進件,該二步進件設於該機體之相對二側,並用以帶動該機體移行,該機身還設有一樞轉連接件及一懸擺件,該樞轉連接件位於該機體前側,且與該懸擺件一端相連接,該懸擺件係可擺動地帶動該樞轉連接件動作;一鑽頭,其一端樞設於該樞轉連接件,且由該懸擺件控制該鑽頭相對該機身呈上、下擺動;及一控制組,結合於該機身,並用以驅使該機身與該鑽頭之作動。1‧‧‧機身11‧‧‧機體12a、12b‧‧‧步進件121‧‧‧主動輪122‧‧‧被動輪123‧‧‧鏈條124‧‧‧撥動片125‧‧‧惰輪13、13’、13”‧‧‧驅動件14‧‧‧樞轉連接件15‧‧‧懸擺件16‧‧‧動力件2‧‧‧鑽頭21‧‧‧桿身22‧‧‧旋片S‧‧‧尖端3‧‧‧控制組4‧‧‧感測器T‧‧‧齒牙
